  • Which polymer is used as thickener in the presence of Ca2+ or Na+?
  • Hydrophobic-associated polymer is widely used as thickener in the presence of Ca 2+ or Na +. Three polymers including partially hydrolyzed polyacrylamide (HPAM) and hydrophobically associating polymers (CHAP and CBHAP) were used to clarify the thickening mechanism.
  • What is copper-catalyzed controlled polymerization of acrylamide?
  • CC-BY 4.0 . Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
  • Can polyacrylamide be used alone in coagulation-flocculation process?
  • Based on a cost evaluation, polyacrylamide use is economically feasible for treating pulp and paper mill wastewater. Results suggested single-polymer systems can be used alone in the coagulation-flocculation process due to polyacrylamide efficiency.
  • Is acrylamide copolymer an enhanced oil recovery Chem?
  • Herein, we report a novel acrylamide copolymer with antimicrobial property as an enhanced oil recovery chem. The copolymer was synthesized from acrylamide (AM), acrylic acid (AA) and 2- ( (2- (acryloyloxy)ethyl)dimethylammonio)ethyl sulfite (ADMES) using oxidn.-redn. initiation system.
